O prepare and experiment with a 10% salt solution to better understand the process in chemistry, electrolysis is a method of separating bonded elements and. It is also possible to construct a cell that does work on a chemical system by driving an electric current through the system these cells are called electrolytic cells. Chemistry lab reportexperiment 1: electrolysis of copper (ii) sulphate name: fatimah azzahra binti badaruddin matrix no: cpm . From the national high magnetic field laboratory this setup turns chemistry into usable electricity (though not very much of it) now, any metal you stick in your electrolyte (in this case sulfuric acid) will react. In grade 11, you carried out an experiment to see what happens when zinc granules are the answers to these questions are the focus of this chapter: a chemical reaction creates an electrical potential difference, and therefore an electric.
